Engineering Team, which is subscribed to OpenStack Dashboard (Horizon). https://bugs.launchpad.net/bugs/1360139 Title: Live migration hosts dropbox should contain service host Status in OpenStack Dashboard (Horizon): In Progress Bug description: To populate the available hosts in the live migration form, horizon use hypervisor hostname else nova api want the service host, which is not the same thing. openstack_dashboard/dashboards/admin/instances/forms.py: def populate_host_choices(self, request, initial): hosts = initial.get('hosts') current_host = initial.get('current_host') host_list = [(host.hypervisor_hostname, host.hypervisor_hostname) for host in hosts if host.service['host'] != current_host] ... More details: ========== When using libvirt, this later when asked about hostname i.e. "$ virsh hostname", it will always return a fqdn (https://github.com/c4milo/libvirt/blob/0eac9d1e90fc3388030c6109aeb1f4860f108054/src/libvirt.c#L1610), which is what nova will set as hypervisor_hostname (https://github.com/openstack/nova/blob/f0a43555b79fe3161933bc01d6bb79f1e622bec2/nova/virt/libvirt/driver.py#L4008) in the NovaCompute table (https://github.com/openstack/nova/blob/f0a43555b79fe3161933bc01d6bb79f1e622bec2/nova/db/sqlalchemy/models.py#L97). In the other hand the service (nova-manage service list) will return the host as the hostname of the compute node i.e. "$ hostname " (https://github.com/openstack/nova/blob/f0a43555b79fe3161933bc01d6bb79f1e622bec2/nova/db/sqlalchemy/models.py#L67). In platform that make a difference between hostname and fqdn i.e. a call to "$ hostname" and "$ hostname -f" return different things, both fields service.host != compute_node. hypervisor_hostname will be different. As for Nova API, this later accept the service.host, at least that how it validate the destination host passed (https://github.com/openstack/nova/blob/f0a43555b79fe3161933bc01d6bb79f1e622bec2/nova/conductor/tasks/live_migrate.py#L85 https://github.com/openstack/nova/blob/f0a43555b79fe3161933bc01d6bb79f1e622bec2/nova/db/sqlalchemy/api.py#L488) To manage notifications about this bug go to: https://bugs.launchpad.net/horizon/+bug/1360139/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
